Day-Ahead Market May Be Delayed in California

LCG, Nov. 1, 2002--A Federal Energy Regulatory Commission ruling that a day-ahead market be put in place in January by the California Independent System Operator will not be satisfied, the state grid operator has told the federal agency.

According to the ISO, the timetable imposed by the FERC will create liability exposure and the possibility of a poorly designed set of market rules. The FERC ruled in early October that it would not allow a proposed delay of a day-ahead market for CAISO, until mid-2003. The ISO has run an hour-ahead market, but not a day-ahead market, which was formerly the responsibility of the defunct California Power Exchange.

The FERC believes that generation resources and transmission capacity can be matched more dependably with a day-ahead market. In order to implement the FERC's deadline, the ISO will need to relax restrictions concerning submittals of balanced schedules, which indicate the providers and consumers making up each side of a transaction. "Following the Oct. 11 order, the California ISO has re-examined the feasibility of relaxing the balanced schedule requirement and the market separation rule and conlcuded that it is impossible to do so by Jan. 31, 2003," the grid operator stated.

In expressing the ISO's attitude towards the January deadline, ISO spokesman Gregg Fishman indicated that a more comprehensive, complex set of provisions for the day-ahead and hour-ahead markets the ISO will be required to implement at an as-yet-unspecified date should be its goal, without the ISO's having to rush to an intermediate version before the ISO is ready. "If you are making plans to remodel your entire kitchen in the spring, why are you spending time painting it in the fall," Fishman said.
